Original abstract

This contribution deals with the issue of residual stresses in particulate ceramic composites used in microelectronics. Residual stresses are developed in the composite due to cooling during manufacturing process. Different coefficients of thermal expansions of particles and matrix cause important residual stress in the composite influencing their behaviour. The main aim of this paper is to determine influence of particle size, distribution, shape, orientation and material properties on magnitude and distribution of residual stresses in the composite matrix. Three dimensional numerical model and finite element method is used for extended numerical simulations. Results obtained contribute to a better understanding of distribution of residual stresses and fracture processes in the studied type of composite.
